r CUTTING APPARATUS FOR SHEETS CONTAINING PRINTED MATTER.

Application iiled April 24, 1899. Serial No. 714,288. (No model.)

. of times in separate forms and to print from the different forms at the same operation of the press, afterward cutting up the sheetson which the diierent impressions are made into sections or strips, each section or strip containing a single impression. This is not only very convenient, but extremely economical when a large number of printed articles areto be produced. It is particularly useful in printing cards, tickets, andthe like which are small in size in that it reduces thepresswork necessary to their production to a minimum. Considerable difculty, however, has been met with in cutting the sheets containing the different impressions tothe exact size desired and in so locating the cuts that the different sections will have the impressions thereon properly1 located. Especially is this the case when the sheets are printed on rotary presses and the sheets are in the form of long narrow strips. This diiiiculty is due to the tendency of the sheets when placed in piles to crawl, thereby making some of thev piles wider or narrower than others, orto a tendency of one part of the pile to crawl more than another when the pile is subjected to frequent clampings and bodily movements, making the pile wider or narrower at the top than at the bottom. This crawling action will almost invariably take place when a large number of cuts are to be made, especially if the material on which the printing is done be cardboard, the glazed surface of` which permits the slipping of the sheets one upon the other.

My invention is designed to overcome the difficulties and inconveniences above noted; and it consists of the novel features of construction and combinations of parts, which will be hereinafter more fully described and claimed.

Eig. 2 is a plan view of the bed of the cutter with my improvements applied. Fig. 3 is a face view of one of the printed sheets or strips. Fig. 4 is a detail perspective View of the cutter-bed. Fig. 5 is a similar View of the slide, and Fig. G is a perspective View showing a pile of sheets or strips onthe slide in position to be cut.v

Like reference-numerals indicatelike parts in the different views.

. In carrying out my invention I provide at a convenient point in the form-cylinder 1 a punch 2, which registers with a die 3' in the impression-cylinder 4, so that as the sheets or strips are fed between said cylinders for the purpose of printing said punch will cut or nip out a hole 5, which hole will of course occupy on each sheet exactly the same relative position with respect to the printed mat- In addition to the punching mechanism on the printing cylinders 1 and 4 I provide certain,improvements in the cutter, as clearly illustrated in the drawings. The bed 6 of the cutter is provided with parallel longitudinally-extending guide-fianges 7 7 on its upper side, between which is located and adapted to move a slide or supplemental bed S, the same being provided with an upwardly-extending register-pin 9 at one end thereof. Said slide is further provided at regular intervals throughout its length with transversely-extending parallel cuttingsticks 10 10, which are inlaid in the slide and lie flush with the uppervsurface thereof. Against these sticks the cutting-blade 11 is adapted to act, the same serving to prevent dulling the edge thereof. Along one side oi' the slide 8 and extending upwardly therefrom are guide-pins 12 12, the same being arranged in line with each other and preferably at equal distances from the side edge of the slide. The said slide is further provided on the edge opposite that along which the guidepins are arranged with a series of ratchetteeth 13, which are adapted to be engaged by a pawl14. The said pawl is pivotally mounted upon a bracket 15, adjustably secured to the bed 6 by means of a screw 16, which eX- IOO tends through an elongated slot 17 in said bracket. Saidbracketisadaptcd tobe moved when said screw is loosened by means of a milled nut 1S, which engages a threaded shank 1f) on said bracket'. The pawl 1t is normally held in position to engage the teeth 13 by means of a spring 20, which is secured to said pawl and to the bracketl. A handle 21 is provided on the slide 8, by means of which the same may be operated, and a stop 22 is secured to the hed,against which the pawl 1l is adapted to bear.

After the hole 5 has been punched in the sheets containing the dilferent impressions said sheets are piled upon the slide 8, with the register-pin 9 thereon extending through the holes 5 therein and with the side edges of said sheets in contact with the guide-pins l2 12, the same being held in this position by means of a clampof any suitable form or construction. It being now desired to cut the sheets in the pile into sections, the cuttingblade 1l is actuated .and the sheets are severed along the line ot the tirst cutting-stick 10 on the slide S. The said slide is then moved outwardly by means of the handle 2l until the pawl l1- passes from one of the teeth 13 to the next one or slightlybeyoud it. The said slide is then moved inwardly, so as to bring the engaging end of the pawl let in contact with the shouldered portion of the tooth 1S with which it has been brought into engagement. \Vhen in this position, the actuation of the cutting-blade l1 will sever the sheets in the pile along the line of the second cutting-stick 10, it being ot course understood that the teeth 13 are soar-ranged on the slide S that the distance between them is ex actly equal to the width or length of the sections into which the sheets are to be divided. During the outward movement of the slide S it will of course be understood that the pawl 1l will ride over the inclined walls of the teeth 13 in succession and in doing so bc swung upon its pivotal connection with the bracket 15. Vhen, however, the outermost point of a tooth has been passed, said pawl will be returned to its normal position by means of the spring 20. If it be desired at any time to adjust the pawl 1l so as to change the point of severance of the sheets by the cutting-blade 11, the same may be readily done by loosening the screw 16 and moving the bracket 15 by the nut 1S, as heretofore described. \Vhen the proper adjustment of the pawl has been made,the same is locked in adjusted position by the screw 1G.

It will be understood, of course, that the illustration herein and the foregoing description relate to but one embodiment of my invention.

Various changes in the details of construction may be made without departing from the nature or spirit of the invention, and I do not care to be limited to the exa-ct construction shown and described, except as defined by the following claims. For example, other means might be adopted in lieu of thc ratchetteeth lf3 and the pawl 'll for enabling the slide 8 to be fed alternately a certain predetermined distance. I therefore reserve to myself the right to adopt such other means as may he found convenient or expedient.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In cutting mechanism for sheets having slots or perforations therein, occupying the saine relative positions in each sheet, the combination with the bed and the cutting-blade, of a slide on said bed on which a pile of said sheets is placed, a register-pin on said slide extending through the openings in said sheets, and guides for the edges of said sheets, as and for the purpose set forth.

2.

4. In cutting mechanism for sheets having slots or perforations therein, occupying the same relative positions in each sheet, the combination with the bed and the cutting-blade, of a slide on said bed on which a pile of said sheets is placed, a register-pin on said slide extending through the openings in said sheets, guides for the side edges of said sheets, and automatic stopping mechanism for the slide, whereby step-bystep movements of predetermined length inay be imparted to said slide, as and for the purpose set forth.

5. In cutting mechanism t'or sheets having slots or perforations therein, occupying the same relative positions in each sheet, the com bination with the bed and the cutting-blade, of a slide on said bed on which a pile of said sheets is placed, a register-pin on said slide extending through the openings in said sheets, guides for the side edges of said sheets, automatic stopping mechanism for the slide, whereby step-by-step movements of predetermined length may be imparted to said slide, and means for adjusting said stopping mechanism, as and for the purpose set forth.
